Tavon has a gift card for $135 that loses $3 for each 30-day period it is not used. He has another gift card for $115 that loses

MrMuchimi

Answer:

Step-by-step explanation:

let x be the number of 30 day periods

135 - 3x = 115 - 2.50x

135 - 115 = -2.50x + 3x

20 = 0.50x

20 / 0.50 = x

40 = x

135 - 3(40) = 135 - 120 = 15

115 - 2.50(40) = 115 - 100 = 15

they will each be $ 15

==============================

so there are 40 thirty day periods.....40 * 30 = 1200 days

Sean has 5 1/2 cups of grape tomatoes, if each serving is 3/4 of a cup, how many servings of grape tomatoes does Sean have

ollegr [7]

Answer:

7 servings

Step-by-step explanation:

first make 5 1/2 unsimplified, to 11/2. then multiple it by 2 so the denominator is the same as 3/4, making it 22/4. 22/3 is 7 1/4, so he has 7 full servings and 1/4th of a serving.

$\bold{\huge{\underline{ Solution }}}$

<h3>Given :-</h3>

We have given some information in the above table

We have to find the mean, median and mode of the given data.

<h3>Let's Begin :-</h3>

For completion of table you should know the basics formulas :-

For calculating x( mid point)

$\sf{=}{\sf{\dfrac{Sum \:of\: class \:interval }{ 2}}}$

That is,

$\sf{=}{\sf{\dfrac{ = 18 + 25}{2}}}$

$\sf{=}{\sf{\dfrac{ = 43}{2}}}$

$\sf{= 21.5 }$

[ For more calculation ,Please refer the attachment ]

For calculating fx
Multiply frequency and midpoint

$\sf{ fx = frequency {\times} midpoint }$

$\sf{ fx = 8 {\times} 21.5 }$

$\sf{ fx = 172 }$

[ For more calculation please refer the attachment ]

We have to calculate mean, median and mode of the given data

We know that the,

Mean = Sum of all observation / no. of observation

That is

$\sf{ Mean = }{\sf{\dfrac{ {\sigma}fx}{{\sigma}x}}}$

Subsitute the required values,

$\sf{ Mean = }{\sf{\dfrac{ 1811 }{ 187.5}}}$

$\sf{ Mean = 9.65}$

Hence, The mean of the given data is 9.65

<h3>For Median </h3>

We know that, For odd numbers

$\sf{ Median = l + }{\sf{\dfrac{ (n/2 - c)}{ f}}}{\sf{ h }}$

Here,

$\sf{ n = }{\sf{\dfrac{ 50 + 1}{ 2}}}$

$\sf{ n = }{\sf{\dfrac{ 50 }{ 2}}}$

$\sf{ n = 25 }$

Lower limit = 34
c = 20
f = 14
h = 41 - 34 = 7

Subsitute the required values in the above formula :-

$\sf{ Median = 34 + }{\sf{\dfrac{ (25-20)}{ 14}}}{\sf{ 7 }}$

$\sf{ = 34 + }{\sf{\dfrac{ 5}{ 14}}}{\sf{ {\times}7 }}$

$\sf{ = 34 + }{\sf{\dfrac{ 35}{ 14}}}$

$\sf{ = 34 + 2.5}$

$\sf{ = 36.5 }$

Hence, The median of the given data is 36.5 .

We know that,

$\sf{ M= l }{\sf{\dfrac{ (f1 - fo)}{ 2f1 - fo - f2 }}}{\sf{ {\times} h }}$

lower limit = 34
f1 = 14
fo = 12
f2 = 12
H = 7

Subsitute the required values,

$\sf{ M= 34 }{\sf{\dfrac{ (14 - 12)}{ 2(14)- 12 - 12 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 2}{ 28 - 24 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 2}{ 4 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 1}{ 2 }}}{\sf{ {\times} 7 }}$

$\sf{ M= 34{\times}}{\sf{\dfrac{ 7}{ 2 }}}$

$\sf{ M= 34 + 3.5 }$

$\sf{ M= 37.5 }$

So, 

Mode = 37.5

Hence ,The mode of the given data is 37.5 .

Please anyone answer this for me?

vlabodo [156]

Im not sure but

(sarah + tara)/2 = 8

(20 + tara)/2 = 8

20 + tara = 16

tara = 4hours ?? it doesn’t make logical sense but this is the only way i can think of

sorry if this wasn’t helpful ;-;
